HOSE-BRIDGE.

SPECIFICATION forming part of Letters Patent No. 595,144, dated December7, 1897.

Application filed March 25, 1897.

To all whom it may concern.-

Be it known that we, J AMES S. CAMPBELL and J AMES V. SHIELDS, citizensof the United States of America, residing at Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Hose-Bridges, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-bridges, and has for its object to construct a hose-bridge that maybe readily secured to the track of streetrailways and the like in orderto permit the cars to pass over the hose, which may be laid across thetrack without injury to same and to this end the invention consists inthe novel construction, combination, and arrangement of parts to behereinafter more specifically described, and particularly pointed out inthe claim.

The invention further aims to construct a hose-bridge of this naturethat will be extremely simple in its construction, strong, durable,effectual in its operation, and comparatively inexpensive tomanufacture, and in describing the invention in detail reference is hadto the accompanying drawings, forming a part of this specification, andwherein like figures of reference indicate similar parts throughout theseveral views, in which- Figure 1 is a perspective view of our improvedhose-bridge in position on the rail and showing the connecting-bracesbroken away. Fig. 2 is a sectional view of the bridges on each rail,said view being taken on a line coinciding with X X 011 Fig. 1. Fig. 3is a view taken on the line Y Y of Fig. 1.

Referring now to the drawings by reference-figures, 1 denotes the bridgeproper, which is provided with a central cut-away portion 2 on itsunderneath face, said bridge being tapered from its center toward eachend and having located at each side of the cut-away portion on its innerface down- Serial No. 629,155. (No model.)

wardly-projecting lugs 3, forming standards which are. adapted to reston the flange 4 of the rail, while the underneath face of the bridgerests upon the tread 5 of the rail. The inner face of the bridge is thusin perfect alinement with the inner edge of the tread of the rail, sothat the car will pass easily over the bridge. The bridges of each railare secured together by means of connecting-braces 6, provided with Tends 7, apertured to receive fastening-bolts S, which are secured bynuts 9, said bolts also receiving a clamp 10, which engages the treadportion of the rail and assists in holding the bridge rigid and in firmengagement with the rail. It will be observed that by this constructionand arrangement of parts the bridge may be readily placed in position onthe rails and quickly secured, the hose being passed through thecut-away portions, thus permitting the car to ride over the same withperfect safety to the hose.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desireto secure by Letters Patent, is-

A hose-bridge consisting of the bridge proper, having an inclined facetapering from the center to each end, said bridge provided with acut-away portion to receive the hose, supporting-standards for saidbridge, combined with the connecting-braces having T ends to receive thefastening-bolts and clamps carried by said bolts to engage the rail,substantially as shown and described.

In testimony whereof we afiix our signatures in presence of twowitnesses.
